The differential cross-section for elastic scattering pi /sup -/ was determined on the basis of 1,421 events observed in a propane bubble chamber. The angular distribution presents a backward bump ( theta > 90 deg ) of (31.5 plus or minus 1.3)%. The amplitude at 0 deg obtained by extrapolating the angular distribution by means of a least squares fit is compared with the value obtained from the dispersion relations and the optical theorem. Values of the pionproton cross-sections were taken into account for the dispersion relation integrals. Using the same best fit of the angular distribution, a value for the interaction radius is obtained from considerations based on the diffraction scattering part. (auth)
